Computing of volume of excavation areas by digital close range photogrammetry

الملخص EN

-Performance of volume calculation by digital close range photogrammetry has been investigated.

The potential use of 3D photomodelling in volume calculation of complex objects which may not be accessible and are sometimes in a risky location was studied using an excavation area and a natural hill as examples.

The volumes obtained from 3D photomodels of objects were compared with the volumes calculated using geodetic techniques.

The results were analyzed with respect to time, cost, and accuracy.

It was found that the photogrammetric method has advantages of 21.89 % in time, 12.11 % in accuracy, and 33.33 % in cost as compared to the classical method.
